This model is non-condensing, so it’s slightly less efficient compared to condensing units that can save more energy by utilizing exhaust heat. While there is an option for WiFi control via an additional module, it’s not included, so extra cost and setup are needed for smart home features. This water heater suits users looking for reliable, consistent hot water without a large tank, particularly if they prefer natural gas and have space limitations. Those wanting maximum energy savings or smart features might want to consider other models or budget for the extras.
